Panasonic 7-14mm: mint condition, includes front and rear caps. Don't have the original box but will pack securely in a Panasonic 14-140mm box. Amazing sharpness all the way out to very wide corners. [sold]

Nope I didn't do the gel filter mod. Before I acquired the lens I thought I might need to, having read all about the purple flare issue. But having shot this lens in a variety of lighting conditions and scenarios I rarely found unusual or excessive flare to be an issue.
